It seems from the list archive that NetBSD 1.5 works on the 3000/300 without
resorting to the serial console, but when I boot the install kernel (I'm using
the cdhdtape image) it gets through the boot process up until
scc0 at ioasic0 offset 0x100000
at which point it gives me
SWITCHING TO SERIAL CONSOLE!
How can I make it stop doing this?
